As per the question there are 9 married couples and no husband and wife should play in the same game:
We know that in a mixed double match there are two males and two females.
Step I: Two male members can be selected in ⁹C₂ = 36 ways.
Step II: Having selected two male members, 2 female members can be selected in,
⁷C₂ = 21 ways.
Step III: Two male and two female members can arranged in a particular game in 2 ways.
Total number of arrangements
= 36 × 21 × 2
= 1512 ways
